This is what nightmares are made of. Seriously. We're never going to squash a spider ever again. 

Watch this video out of Australia where a person sees a massive wolf spider crawling across their floor. Obviously freaked out by the demon spawn, they feel the need to squash it and kill it immediately (as we all would).

Well, it turns out that the spider was a female... a pregnant female. What happened next will haunt your dreams.

The good news, we suppose, is that wolf spiders generally won't bite you unless they're continually provoked. Even if you do get bit by one, their venom will only cause swelling, mild pain, and itching.
